Boric acid manufacturers in China by using the method of boron ore producing boric acid - Appropriate chemical industry

boric acid manufacturer in China of boron ore is mainly used to produce boric acid, boron ore belongs to the scarce mineral resources, boron deposits in China are mainly distributed in liaoning, qinghai and Tibet and other regions, boric acid manufacturer also is according to the presence of boron ore and a large amount of together.

boric acid manufacturers in China by using the method of boron ore producing boric acid mainly include sulfuric acid method, carbon ammonia method and two-step method and the method of sodium borate. This is several kinds of boric acid factory after a lot of improvement and change is still in production methods.

acid method is China's earliest production of boric acid manufacturer of boric acid method, at the beginning of China's mining boron ore grade is high, more suitable to production by sulfuric acid method. The sulfuric acid method is direct decomposition of boric magnesium ore to preparing boric acid, boric acid after manufacturers using fractional crystallization separation of boric acid and magnesium sulfate and other substances.

carbon ammonia method is boric acid production of boric acid in solution first, and then heated deamination to get boric acid, decomposition of ammonia can be recycled after absorb carbon dioxide.

two footwork is now boric acid factory main production methods of two-step mainly refers to the first will get the borax, boron ore after real after neutralization using sulfuric acid or nitric acid and borax, repass crystallization, separation and drying and so on a series of steps to get the boric acid products. The benefits of this approach a lot and have been improved a lot of boric acid manufacturer.

sodium borate method is more boric magnesium ore roasting ore crushed into a certain size, according to the lower than the theoretical amount of alkali than with soda solution into the appropriate liquid-solid ratio of slurry, in specific carbon alkali decomposition temperature and pressure, after filtering, washing sulfuric acid neutralization, finally made boric acid product, process is very complex, but the production of the product purity is high.

boric acid manufacturer in the production of boric acid method has been improved, boric acid manufacturer in our country should actively introduce the foreign advanced technology of boric acid, mutual confluence, import boric acid to the competition.
